Abstract
An antenna apparatus in which a combination of rectangular waveguidesandand a combination of rectangular waveguidesandare disposed bilateral symmetrically to each other, and a waveguide orthomode transduceris disposed above a waveguide orthomode transduceris provided. Therefore, the profile of the antenna apparatus can be reduced and the stability of installation of the antenna apparatus can be improved without impairing the electric characteristics of the antenna apparatus. Since the antenna apparatus has a bilateral symmetric structure, it excels in weight balance and offers stable performance from the viewpoint of mechanism.
